Subject: [PATCH] Add support for prop overrides

The format of the overrides is KEY=VALUE
Where KEY is one of the dict keys used in config
https://cs.android.com/android/platform/superproject/main/+/main:build/soong/scripts/gen_build_prop.py
And VALUE is the value you want take over.

An example:
PRODUCT_BUILD_PROP_OVERRIDES += \
    BuildDesc="jfltevzw-user 4.2.2 JDQ39 I545VRUAMDK release-keys" \
    BuildFingerprint=Verizon/jfltevzw/jfltevzw:4.2.2/JDQ39/I545VRUAMDK:user/release-keys \
    DeviceName=jfltevzw \
    DeviceProduct=jfltevzw \
    SystemDevice=jfltevzw \
    SystemName=jfltevzw
